The identification of the machine was possible after its number was discovered. The experts examined all the photos of the Buk system taken in the separatist-controlled areas of Ukraine and compared them to those of the complex stationed in Russia.

"We can say with confidence that on 17 July 2014, the Russian Buk TELAR numbered 332 of the 53rd Anti-Aircraft Missile Brigade based in Kursk was filmed and photographed in eastern Ukraine. This specific Buk, previously identified as Buk 3×2, was filmed moving to the center of the launch area estimated by the Dutch Safety Board for the missile that downed MH17", Bellingcat journalists concluded in the report.

Earlier Bellingcat expert Aric Toler said the identification number of the Buk seen in the Donets region was recovered. It was 332. This fact confirmed the vehicle originated from Russia's 53rd Anti-Aircraft Missile Brigade of Kursk.
